ospf實驗

 

1、拓撲

 

 

 

2、地址規劃（ipv4）

路由	接口	地址	Loopback0
R1	F0/0	10.102.10.1/24	10.102.1.2/24
	F0/1	10.102.20.1/24
R2	F0/1	10.102.10.2/24	10.102.2.2/24
	F0/0	10.102.30.2/24
R3	S1/2	10.102.40.3/24	10.102.3.2/24
	F0/0	10.102.10.3/24
R4			10.102.4.2/24
R5	S1/0	10.102.40.2/24	10.102.5.2/24
R6	S1/1	10.102.40.1/24	10.102.6.2/24
R7	F2/0	10.102.30.1/24	10.102.7.2/24
	F0/1	10.102.20.2/24
	F0/0	10.102.50.2/24
R8	F0/0	10.102.50.1/24	10.102.8.2/24

 

3、配置步驟

採用幀中繼鏈接，R4做爲幀中繼交換機

R4#configure terminal

R4(config)#frame-relay switching

R4(config)#interface serial 1/0

R4(config-if)# encapsulation frame-relay

R4(config-if)#no arp frame-relay     關閉動態dicl

R4(config-if)# frame-relay lmi-type cisco   

R4(config-if)# frame-relay intf-type dce    

R4(config-if)# frame-relay route 201 interface Serial1/1 101     配置幀中繼路由表

R4(config-if)#frame-relay route 202 interface Serial1/2 402

R4(config-if)#exit

 

R4(config)#interface serial 1/1

R4(config-if)# encapsulation frame-relay

R4(config-if)# frame-relay lmi-type cisco   

R4(config-if)# frame-relay intf-type dce    

R4(config-if)# frame-relay route 101 interface Serial1/0 201      配置幀中繼路由表

R4(config-if)#frame-relay route 102 interface Serial1/2 401

R4(config-if)#exit

 

R4(config)#interface serial 1/2

R4(config-if)# encapsulation frame-relay

R4(config-if)# frame-relay lmi-type cisco  

R4(config-if)# frame-relay intf-type dce    

R4(config-if)# frame-relay route 401 interface Serial1/1 102     配置幀中繼路由表

R4(config-if)#frame-relay route 402 interface Serial1/2 202

R4(config-if)#exit

 

R5 R6配置靜態dlci

R5#configure terminal

R5(config)interface Serial1/0

R5(config-if)# encapsulation frame-relay

R5(config-if)#no arp frame-relay    關閉動態dicl

R5(config-if)# frame-relay map ip 10.102.40.1 201 broadcast    

R5(config-if)# frame-relay map ip 10.102.40.3 202 broadcast     

R5(config-if)#exit

 

R6#configure terminal

R6(config)#interface Serial4/1

R6(config-if)# encapsulation frame-relay

R6(config-if)#no arp frame-relay    關閉動態dicl

R6(config-if)# frame-relay map ip 10.102.40.3 102 broadcast  

R6(config-if)# frame-relay map ip 10.102.40.2 101 broadcast  

R6(config-if)#exit

 

測試連通性：

R5#ping 10.102.40.3

 

 

R6#ping 10.102.40.3

 

 

 

4、配置ospf

R2配置以R1爲例：

R1#conf terminal

R1(config)#router ospf 1

R1(config-router)# router-id 1.1.1.1

R1(config-router)#area 1 nssa                 定義區域1爲nssa區域

R1(config-router)#network 10.102.1.0 0.0.0.255 area 0    宣告直連網段

R1(config-router)# network 10.102.10.0 0.0.0.255 area 0

R1(config-router)# network 10.102.20.0 0.0.0.255 area 1

R1(config-router)#exit

 

5、 幀中繼配置Ospf

R5參照R6配置

R6#configure terminal

R6(config)#router ospf 1

R6(config-router)#router-id 6.6.6.6

R6(config-router)# network 10.102.40.0 0.0.0.255 area 2

R6(config-router)#exit

R6(config)interface Serial1/1

R6(config-if)# ip ospf priority 0   設置端口優先級爲0，不參於選舉。

R6(config-if)# exit

 

R3#conf terminal

R3(config)#router ospf 1

R3(config-router)# router-id 3.3.3.3

R3(config-router)#network 10.102.3.0 0.0.0.255 area 0   宣告直連網段

R3(config-router)#network 10.102.10.0 0.0.0.255 area 0

R3(config-router)#network 10.102.40.0 0.0.0.255 area 2

R3(config-router)#neighbor 10.102.40.2   手動配置R5,R6爲鄰居

R3(config-router)# neighbor 10.102.40.1

R3(config-router)# area 0 range 10.102.0.0 255.255.0.0  

R3(config-router)#exit

 

 

 

查看鄰居狀態

R3#show ip ospf neighbor  

 

 

6、配置rip 重發布到ospf

R7#configure terminal

R7(config)router ospf 1

R7(config-router)#router-id 7.7.7.7

R7(config-router)#area 1 nssa

R7(config-router)# network 10.102.20.0 0.0.0.255 area 1    宣告直連網段

R7(config-router)# network 10.102.30.0 0.0.0.255 area 1

R7(config-router)#redistribute rip metric 25 subnets    將RIP重發布到ospf

R7(config-router)#exit

R7(config)#router rip

R7(config-router)#version 2

R7(config-router)# network 10.0.0.0

R7(config-router)#no auto-summary

R7(config-router)#redistribute ospf 1 metric 4        將ospf重發布到Rip

 

測試連通性：R8 ping R6

R8#ping 10.102.40.1

 

 

 

 

R8 ping R5

R8#ping 10.102.40.2

 

 

R1#ping 10.102.40.3

 

 

完成ping測試，則ospf配置已經成功。

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

OSPFV3配置

 

 

1、ipv6地址規劃

 

路由	接口	地址	Loopback0
R1	F0/0	2001:db8:102:3::1/64	2001:cf:102:1::1/64
	F0/1	2001:db8:102:4::1/64
R2	F0/1	2001:db8:102:3::2/64	2001:cf:102:2::1/64
	F0/0	2001:db8:102:5::1/64
R3	S1/2	2001:db8:102:1::3/64	2001:cf:102:3::1/64
	F0/0	2001:db8:102:3::3/64
R4			2001:cf:102:4::1/64
R5	S1/0	2001:db8:102:1::1/64	2001:cf:102:5::1/64
R6	S1/1	2001:db8:102:1::2/64	2001:cf:102:6::1/64
R7	F2/0	2001:db8:102:5::2/64
	F0/1	2001:db8:102:4::2/64	2001:cf:102:7::1/64
	F0/0	2001:db8:102:2::2/64
R8	F0/0	2001:db8:102:2::1/64	2001:cf:102:8::1/64

 

 

2、配置步驟

採用幀中繼鏈接，R4做爲幀中繼交換機，幀中繼路由R3,R5,R6靜態配置dlci

 

R3#configure terminal

R3(config)#ipv6 unicast-routing

R3(config)#interface Serial4/2

R3(config-if)# frame-relay map ipv6 2001:DB8:102:1::1 402 broadcast

R3(config-if)# frame-relay map ipv6 2001:DB8:102:1::2 401 broadcast  

R3(config-if)#frame-relay map ipv6 FE80::CE01:1EFF:FE28:0 401 broadcast

R3(config-if)# frame-relay map ipv6 FE80::CE02:EFF:FE60:0 402 broadcast  

R3(config-if)#exit

 

R5#configure terminal

R5(config)#ipv6 unicast-routing

R5(config)interface Serial1/0

R5(config-if)#frame-relay map ipv6 2001:DB8:102:1::3 202 broadcast

R5(config-if)#frame-relay map ipv6 2001:DB8:102:1::2 201 broadcast

R5(config-if)# frame-relay map ipv6 FE80::CE01:1EFF:FE28:0 201 broadcast

R5(config-if)# frame-relay map ipv6 FE80::CE04:19FF:FE18:0 202 broadcast

R5(config-if)#exit

 

R6#configure terminal

R6(config)#ipv6 unicast-routing

R6(config)interface Serial1/1

R6(config-if)# frame-relay map ipv6 2001:DB8:102:1::3 102 broadcast

R6(config-if)# frame-relay map ipv6 2001:DB8:102:1::1 101 broadcast

R6(config-if)#frame-relay map ipv6 FE80::CE04:19FF:FE18:0 102 broadcast

R6(config-if)#frame-relay map ipv6 FE80::CE02:EFF:FE60:0 101 broadcast

R6(config-if)#exit

 

測試連通性：

R6 ping R3

R6#ping 2001:db8:102:1::3 

 

 

 

幀中繼環境下配置ospf

R3#configure terminal

R3(config)#ipv6 router ospf 1

R3(config-rtr)#router-id 3.3.3.3    配置路由id

R3(config-rtr)# area 0 range 2001:DB8::/32

R3(config-rtr)# exit

R3(config)#interface Serial1/2

R3(config-if)#ipv6 ospf 1 area 2

R3(config-if)# ipv6 enable

R3(config-if)# ipv6 ospf neighbor FE80::CE02:EFF:FE60:0 priority 1    手動配置鄰居

R3(config-if)# ipv6 ospf neighbor FE80::CE01:1EFF:FE28:0  priority 1

R3(config-if)#exit

R3(config)#interface fastEthernet 0/0

R3(config-if)#ipv6 ospf 1 area 0

 

R6配置參考下面R5配置

R5#configure terminal

R5(config)#ipv6 router ospf 1

R5(config-rtr)#router-id 5.5.5.5      路由id

R5(config-rtr)# exit

R5(config)#interface Serial1/0

R5(config-if)# ipv6 ospf 1 area 2

R5(config-if)# ipv6 enable

R5(config-if)#exit

 

配置其餘區域的OSPFV3

R2參考R1配置

R1#configure terminal

R1(config)#ipv6 unicast-routing

R1(config)#ipv6 router ospf 1

R1(config-rtr)#router-id 1.1.1.1

R1(config-rtr)#area 1 nssa 定義區域1爲nssa區域

R1(config-rtr)#exit

R1(config)#interface fastEthernet 0/0

R1(config-if)#ipv6 enable

R1(config-if)#ipv6 ospf 1 area 0

R1(config-if)#exit

R1(config)#interface fastEthernet 0/1

R1(config-if)#ipv6 enable

R1(config-if)# ipv6 ospf 1 area 1

R1(config-if)#exit

 

 

 

配置路由重發布

R7#configure terminal

R7(config)#ipv6 unicast-routing

R7(config)#ipv6 router rip ys

R7(config-rtr)#redistribute ospf 1 metric 4       將ospfv3重發布到RIP中 R7(config-rtr)# redistribute connected

R7(config-rtr)#exit

R7(config)#ipv6 router ospf 1

R7(config-rtr)# router-id 7.7.7.7

R7(config-rtr)#area 1 nssa

R7(config-rtr)# redistribute rip          將rip重發布到ospfv3中

R7(config-rtr)# redistribute connected    把鏈接 R8 的網段重分佈到 OSPFv3

R7(config-rtr)# exit

 

測試連通性

R8 ping R3

R8#ping 2001:db8:102:1::3  

 

 

查看R5的鄰居：

R5#show ipv6 ospf neighbor

 

 

 

 

實驗總結：

經過這次做業，讓我對於上學期學的ospf知識有了更深的理解，同時結合幀中繼等，動手操做讓目前學習的內容瞭解有了更深的層次。這做業作了兩天半時間，從一開始配置錯誤致使沒法ping通，到後面地址配置錯誤，算錯致使後期排錯排了好久。相信此次做業能對於實操有很是重要的意義。
